Where is the reservoir for the trim plate

I am a new Supra owner. I just purchased a 2006 21 Launch and wondered where the reservoir is for the trim plate. I cannot find it.
Thanks for your help, Dave

On my 2000 Launch direct drive it is under the rear seat between the mufflers

Thanks for your reply, TD in NC, it was not there. I did find it behind a removable small carpeted panel in the rear storage compartment, on the drivers side of my direct drive boat. Thanks again, Dave

Glad you find it, now that you say that, I remember when I was trying to find someone indicated it was located where yours was. Not sure how much is the same between 2000 and 2006 but I have spent some time trying to figure our how to fix things on my own and with the help of the forum. If I can be of any help dont hesitate to send me a message.
